I'm pretty sure I've killed at least 10 robots with their grenades(I counted), yet the counter stopped at 6... so I killed another 3 and it went to 7.

If it matters, I'm doing it on Heavy Metal..and it's not really working.

That was my toughest one to finish. I was at 12/20 at the end of the game and then started grinding it in Heavy Metal. You could take all your teammates powers away so they don't kill the robot. Just get the robot down to a tiny sliver of health, back away from it and wait for the grenade and run up to him and throw it. You will take damage but it will guarantee the hit.

I did, but it's constantly 11/20.

Is it me or does killing Robots in Heavy Metal just not always count?

Try on smaller robots in Inner Base (after cutscene with Herules in room on the left)
